Wait, so it just fails if the MAC isn't known? That's surprising!

D? Really? That seems excessive for a ping.

C sounds plausible, but I’m not so sure about that.

I think B makes more sense. The PE node should respond.

A is correct. The MAC needs to be known in the FDB.

I feel like all nodes replying sounds too broad, so I’m hesitant about option D. I think it’s more about specific responses.

I’m a bit confused. I thought the request would go to the CE device, which makes me think option C could be right, but I need to double-check.

I remember something about flooding in VPLS, so maybe option B is correct? It sounds familiar from practice questions.

I think the oam mac-ping needs the MAC address to be in the local FDB, so I'm leaning towards option A, but I'm not entirely sure.

Hmm, I'm a bit confused about the "full mode" part of the instructions. I'll need to make sure I understand what that means and how it affects the Snort output.

Ah, I remember learning about this in class. The Sprint Backlog is made up of the granular Tasks that need to be completed, and those are the items that get estimated in hours. I feel good about selecting that option.

Okay, I've got this. The answer is clearly to use the voting buttons in the email. That way, Sam can see who has responded and what their preferences are.
